Control MCU(RX651)
The RX651 MCU board is equipped with RX651 for PLC control. The following tables show the control MCU
terminal connection information. For unused pin settings, set the ports to "Input" since the signals connected
to CPX3 have the pin assignments on the CPX3. Also, use the MCU on-chip pull-up function to set other
signal terminals.
